The software architecture according to claim 18, wherein the driver matching the type information comprises at least one of a usb device driver, a network device driver, an analog video signal receiving conversion driver, and a digital video signal receiving conversion driver, and the driver layer is provided with a type detection driver for detecting the type information.

20. The software architecture according to claim 19, wherein the driver layer further includes a plug detection driver, the plug detection driver is configured to detect a plug event generated by plugging a video interface female connector and a video interface male connector, and the type detection driver is configured to detect the type information when the plug detection driver detects the plug event.

21. The software architecture according to claim 18, wherein said camera hub layer comprises a parameter and command conversion center, a control service, a status monitoring service, a status reporting center, a frame data processing service, and a camera device pool, the parameter and command conversion center is used for receiving the control instruction transmitted by the camera server and converting the control instruction into a control instruction matched with the camera, the control service is used for maintaining a control instruction sequence and a state machine, the state monitoring service is used for receiving the state data, the state reporting center is used for reporting state transition information to the camera server when the state monitoring service monitors the state data transition, the frame data processing service is used for receiving the video frame data and processing the video frame data, and the camera equipment pool is used for storing the external equipment nodes.

22. A method for implementing a software architecture, applied to the software architecture of claims 18-21, the method comprising:

23. The method of claim 22, further comprising: and if the plug detection driver detects that the plug event is a plug event, the driver loaded by the driver layer and related to the external equipment is unloaded.

24. The method of claim 22, further comprising:

if the plug detection driver detects that the plug event is a plug event, the camera server detects the external equipment node;

and if the camera server detects the external equipment node, adding the external equipment node to the camera equipment pool to update the camera equipment pool.

25. The method of claim 24, further comprising:

and if the plugging detection driver detects that the plugging event is a plugging event, the camera server removes the external equipment node in the equipment pool.

26. The method according to any one of claims 22-25, further comprising:

calling a camera application program interface to construct a camera client matched with the external equipment node;

the camera server receives the parameters through the camera client and transmits the parameters to the parameter and command conversion center;

the parameter and command conversion center converts the parameters and converts the parameters into parameters matched with the type information;

and the driver matched with the type information sets the parameters matched with the type information into the external equipment.

27. The method of claim 26, further comprising:

the application program layer inputs an instruction for starting the camera to the camera client;

the camera server receives the instruction through the camera client and transmits the instruction to the parameter and command conversion center;

the parameter and command conversion center converts the instruction and converts the instruction into an instruction matched with the type information;

the drive matched with the type information controls the camera through the command matched with the type information;

the driver matched with the type information receives video frame data input by the camera;

the driver matched with the type information uploads the video frame data to a frame data processing service;

the frame data processing service processes the video frame data.

28. The method of claim 26, further comprising:

the drive matched with the type information uploads the state data of the camera to a state monitoring service;

the state reporting center reports state transition information to the camera client through the camera server when the state monitoring service monitors that the state data is changed;

the control service maintains a state machine.
